Abstract
According to current regulations, codes and design manuals, there are no defined calculation methods for widening of railway structure clearance on transition curve.In order to find a less-error and easy-to-use method for widening of railway structure clearance on transition curve, this paper draws and analyzes the widening curve of different curve element combinations, and puts forward the variation rule of widening values of railway structure clearance on transition curve based on the analysis of data of the graphic method.According to the characteristics of the widening curve and by using the method of Polynomial curve fitting, the study presents the general calculation formulas of the inner and outer widening and movement added super-elevation.The comparison with the graphical method shows that the general formula error satisfies the requirement of the measurement error limit and the general formula is correct and reliable.The general formulas can be referenced by the relevant technical personnel of railway in routine work and in the amendment of Railway Technical Management Rules.关键词
